Olympus plans are limited to march 2015, so there are still hopes a new 4/3 camera will come on 1st of April 2015 
Seriously, 4/3 was not born to break the rules of photography, it was made to drive money into Olympus pockets, until it worked it was a good idea to develop it, it obviously does not work anymore (probably never was that much profitable compared to competitors market share)
m4/3 is another approach to reach some (and even more) of the people that did bought into 4/3 system, photographers worried of camera size, but searching something more than a compact are the buyers at which Olympus did aim with m4/3 (previously 4/3)
they got it all wrong instead with 4/3 where the presumed crop factor advantage was never an advantage for most photographers (not much compact), instead it was a limit: resolution, dynamic range, noise and depth of field control was (and is still) inferior to competitors in the same time period.
expensive glass couped with not so good AF system and slow cameras was always driving away the pro or semi-pro users that could eventually appreciate some features of the 4/3 system
there was at least one thread about "this system is doomed" related to the 4/3 system till it was presented (it was in most cases a fanboy game), still it survived almost 7 years and I guess it will be around at least another couple of years,
now it's evident to most that it is nearly a dead end and Olympus is not negating it anymore, as they have hopes in their mirror-less system, the problem is that if this approach is really good and will drive many buyers, the big players will start to play with their rules.
